WILLIAM MOORE, OF WILLIAMSBURG, NEW YORK, ASSIGNOR TO JAMES GARMAN.

DOOR-LOCK.

Specification of Letters Patent No. 9,265, dated September 14, 1852.

To all whom t may concern.'

Be it known that I, VILLIAM MOORE, of Williamsburg, in the county of Kings and State of New York, have invented, made, .and applied to use certain new and useful Improvements in the Construction of Locks, which are specially applicable to hotels and other places where the locking of the door from the inside is required to be permanent, so as to secure the door from all attempts to open it from the outside, but when the door is locked from the outside there is no more security required than `the ordinary box or mortise lock; and I hereby declare that the following is a full, clear, and exactw description of the construction and operation of the same, reference being had to the annexed drawing, making part of this speciication, wherein- Figure 1 is an elevation of the lock complete with the lock plate removed. Fig. 2, is an elevation of the second tumbler and revolving check as applied with the key hole on the inner side of the lock. Fig. 3, is a sectional plan through the two key holes.

The like marks of reference denote the same parts in all the figures.

a, is the box of the lock. This may be so formed as to be used as a box lock, mortise or rim lock.

b, is the cover plate secured by screw 1, as usual.

In Fig. 3, A, is the side of the lock, termed herein the outside, being thatside of the door from which a person usually enters and B, the side where there is the greatest security required, or the side from which a person locks himself into a room.

c, is the square mortise and cylinder for the spindle of the handles-d', is the lever connected to the latch e, as usual. f, isthe bolt head, with the shank f1, setting by a mortise over the stud 2, which also forms the fulcrum for the vertical tumbler g, kept to its place by the spring 7 3 is the notch in the bolt forming the locking and interlocking talons.

4, is the square detent on the tumbler g taking the notches in the bolt as usual.

5, is the key hole in the cover plate, which may be fitted with or without wards in any convenient manner. The end of the key enters a hole in the back plate of the box a, and over this hole is a cover or cap 6, that prevents the key from being entered from the inside, also prevents all access to the key when it is in its proper key hole on the nside and also prevents any person from seeing through the key hole.

The parts thus far operate as usual.

h, is a dividing plate having openings to pass the bolt f1, the latch e, and the tumbler g, and thus shut off all access from the key hole on the outer side to the key hole on the inner side.

z', is the key hole in the box of the lock, through which t-he key is entered from th inner side.

8, is a cap over the hole in the cover plate b, similar to the cap 6.

9 is a second notch in the bolt shank f1, to form the locking and unlocking talons for the key when entered through the key hole z', and the tumbler g, being extended over the key hole z', the bolt can be protruded or retracted from either key hole.

The security of my lock when fastened from the key hole z', depends upon the parts more clearly shown in Fig. 2, where 10 is a stud carrying a revolving check 11, with a stud 12 attached to its outer face near the top which stud 12, passes into an opening or mortise in the vertical sliding tumbler 7c, which is guided between the dividing plate b, and a square continuation of the stud 10.

13, is a detent on the tumbler 7c taking when the bolt is protruded the notch 14.

15 is a spring to press the detent 13 onto the bolt.

, It will now be seen that the key in projecting the bolt takes the lower edge of the tumbler lo, when the key is entered by the key hole z', and as the locking motion is completed the detent 13, taking the notch 14, secures the bolt permanently in its protruded position, and the revolving check tumbler having been partially turned on its center so removes the stud 12, as to allow the tumbler 7c, to descend but on again unlocking the lock, the tumbler 7c, being again raised the revolving check is turned back again taking the top of the mortise in the tumbler 7c, retains the tumbler in its elevated position so that the lock can be locked and unlocked from the outer key hole 5, as often as required without affecting or being obstructed by the tumbler la. It will be seen that no pick or instrument introduced through the key hole 5, can be made to operate on the tumbler 7c, or on the key as it stands in the key hole z', neither can the key be nippered and turned by boring through nated on when looked on the inner side, and

avoids the danger that exists with locks that have two key holes and bolts, that one bolt may maliciously or otherwise be thrown from the outside, while the inner bolt is also protruded preventing the key on the inside from opening the lock, and although two key holes and one bolt have been used with a dividing plate between the two key holes, all the tumblers, have extended into both divisions of the lock, and the ultimate security depended upon parts to protect the outer key hole and prevent any instrument vreaching the tumblers, which are otherwise exposed to`both inner and outer key holes.

The dividing plate being well known is public property, therefore forms no part of my claim neither do I claim any of the parts operated from the outside key hole as these may be of any usual form but t What I desire to secure by Letters Patent 1s- I claim the tumbler la, inclosed by the dividing plate h, to be operated on solely by the key when entered from the inner key hole, in combination with the revolving check or its equivalent and the bolt for the purposes and as described and shown.

In witness whereof Irhave hereunto Set my signature this twenty second day of June one thousand eight hundred and fifty two.

WILLIAM MOORE.
